So I have been having this issue for months now and have basically refreshed the cooling system (new coolant temperature sensor, new thermostat, new coolant, new radiator fan and motor within a fan assembly), but the car still will not start after the third hot start or so. So before I installed the new thermostat, I couldn't hot start the car at all, I'd get the immediate stall. But after I installed the thermostat, I could get a single hot start in before it started stalling again. At this point, I realized the motor for the radiator fan (not the condenser fan) had burned out and caused it not to spin. I bought and installed the new fan assembly and I now get two hot starts before stalling. However, this may not be a cooling issue due to the fact that my engine temperature was normal (or my temperature gauge is broken, I'm not sure). Doing some research, I think the issue may be the idle air control valve, but again I'm not sure due to the fact that the stalling only occurs after several hot starts (like if I was running errands and parking and starting at several locations). Usually the idle will stick around 800 rpm's, but on hot starts where it starts stalling, it'll immediately shut off, or sit at 200 rpm's for a second and then shut off. I know I have a slight coolant leak, but I don't think cooling is the issue. For those who know the blemishes of mid-1990's to early 2000's Honda's might refer to it as heat soak, but again I doubt this being true. So overall, I've heard I need a new fuel pump, or an idle air control valve, or an intake air bypass valve, or a new main relay. Any suggestions on how I can fix this hot start issue?
I am pretty sure that the fuel pump has been replaced once before, but I think the main relay and IACV are OEM and 20 years old if that helps.
have the same problem?
